Problems solved by technology
At present, the protective film of automobile lamps is after the vacuum evaporation of aluminum film is completed, and the surface of the film layer is artificially sprayed with a paint layer in the atmosphere as a protective film, so that the aluminum film layer is bound to be oxidized in the atmosphere, which reduces the performance of the film layer, and The chemical properties of the sprayed chemical coatings are unstable, and there are often serious deficiencies such as color development and yellowing under ultraviolet radiation. In addition, the stability of artificial spraying is not high, which will cause defects such as paint sagging
Restricted by the purification environment, the sprayed protective film often produces particles, which affect the appearance of the lamp
The existing process of aluminum coating and protective film coating of automotive reflectors cannot meet the increasing quality requirements of automotive lamps with the increasing development of the automotive industry

Embodiment Construction
[0010] The process of aluminizing and coating protective film on automobile reflectors such as reflective bowls and decorative rings, which use iron parts, BMC, ABS, PC and other materials as coating base materials, has the following process: a. Surface cleaning, clean water and cleaning solution After that, use ultrasonic waves to clean the surface of the substrate; b. drying, drying the cleaned substrate with an oven; c. spraying primer, spraying primer on the substrate to be coated; d. drying, spraying The substrate after the primer is put into an oven for drying; e. Evaporate aluminum film, put the substrate after spraying the primer and drying it into a vacuum chamber to evaporate aluminum film; f. Coat the protective film, first put the monomer material on In the airtight tank, the temperature is 26-30°C, the pressure is 0.8-0.9 atmospheric pressure, volatilizes into gas, and then fills it into the vacuum chamber according to a certain flow rate, the pressure in the vacuu...

The present invention relates to automobile lamp film coating technology, and is the once completed process of aluminum film and protecting film under vacuum condition for the reflector and decorating ring with iron, BMC, ABS, PC and other base material. The technological process includes surface cleaning, stoving, spraying priming lacquer, stoving, vacuum evaporation to coating aluminum film and vacuum coating of protecting film. The once completion of aluminum film and protecting film can avoid oxidation of the aluminum film and raise film performance and lamp quality.
Description
Technical field [0001] The invention relates to the field of coating technology, in particular to a technology in which iron parts, BMC, ABS, PC and other materials are used as coating base materials for reflective mirrors and decorative rings, which are coated with aluminum and protective film at one time under vacuum conditions. Background technique [0002] The protective film coating process involves a wide range, and it has many applications in the automotive lighting industry and metallized decorative films on the surface of plastic parts. At present, the protective film of automobile lamps is after the vacuum evaporation of aluminum film, the surface of the film layer is sprayed artificially in the atmosphere as a protective film, so that the aluminum film layer is bound to be oxidized in the atmosphere, which reduces the performance of the film layer, and The chemical properties of the sprayed chemical coatings are unstable, and there are often serious deficiencies i...
